[Simulation of a coronary vascular complication in transluminal coronary angioplasty by reversible intima folding].

The injection of contrast material into the right coronary artery via a guiding catheter while a Harzler dilatation catheter had already been introduced revealed an inhomogeneous filling of the vessel suspicious of an extensive thrombosis or a dissection. On completion of the angioplasty and removal of the balloon catheter, the artery again filled homogeneously showing a good angioplasty result. It is concluded that a complication had only been faked during angioplasty due to intimal folding and subsequent flow obstruction following the insertion of the balloon catheter.
